I looked into some examples of sharing data to other apps using content Provider. All these examples talks about sharing sqlite dbs. I need to share data under shared Preferences of my app to other apps using content Provider. Can I use content Provider to do that ?. Please let me know some pointers or sample code to share data other than sqlite db using content provider.

I need to access the shared preference in a background service instead of activity on phone boot up.But getSharedPreferences function is define in the activity, so how can i access the data without creating the activity?

I've written an app with 3 tabs. Each tab has the same list view with different data sources. I have setup SharedPreferences in the tabhost activity, but I put my onSharedPreferenceChangeListener method in my listactivity. When I change a preference, my listener gets called and it updates my database. This is all working. However, if I change the data in tab 1, it calls my listener once. If I change the data for tab 2 it calls it twice and if I change the data in tab 3 it calls it three times. Any idea why it works this way? I guess I could setup my shared prefs in my listactivity and that might avoid the issue, but I'm curious why my listener is called multiple times if it's in a different tab.

I am using a PreferenceActivity to show some settings for my application.I am inflating the settings via a xml file so that my onCreate (and complete class methods).These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity.

I'm using Windows to develop android apps and want to know where user preference data is located. It says at /data/data/package/...., but where can I actually see the preference file? Via eclipse or command line tools?

I'm doing an application that requires that certain thread access data that's shared among it and another service.How can I protect these shared data form accessing in the same time is there anything in android for that or android has nothing to do with this as Java API's will do the job.

Now I have 2 activities that would simultaneously access one data/ settings. However, two kind of solution can be applied after I study from the Android Developer's Guild.One is ContentProvider, The discription in guild is as: "Content providers store and retrieve data and make it accessible to all applications. They're the only way to share data across applications; there's no common storage area that all Android packages can access."and another is SharedPreferences, "To use preferences that are shared across multiple application components (activities, receivers, services, providers), you can use the underlying Context.getSharedPreferences() method to retrieve a preferences object stored under a specific name."

Fabulous or any other ROM/theme creator i was wondering if its possible to maybe link to a guide or a quick explanation or how to make my own icons like for the notification bar? I.e. The battery, 3g... Stuff like that and how to know what size and everything.

Is anyone able to explain to me exactly what the upcoming JIT compiler will provide? For example, I have Java programs that generate bytecode at runtime which I would like to port to android. Will the JIT compiler make this possible by converting the runtime generated Java byte code to Dalvik at runtime as required?

Is there an explanation of the ADT layout editor UI some place? I can't find anything on the Android web site about it. When I look at a layout in the design view, there are a number of fields at the top with labels like MCC, MNC, Lang, etc. I've noticed that I can change the contents of these fields, such as orientation, and it has an effect on the view. But a yellow warning triangle appears next to the field I've changed and the next time I open this view I see the unmodified field. For example, if I change to landscape orientation the view goes back to default next time. Is there documentation some place on what these fields mean and how they are supposed to be used?

Some of my app's preferences could use some more explanation than the scarce space available for the summary. Sadly, there doesn't seem to be support from the system, like an optional help button that shows a longer text. How do you solve this problem? The first thing that comes to mind is an additional custom "preference" like "more information to above entry" that opens an AlertDialog with the help text, but that's not really nice for both user (two entries for the same preference) and the developer (manual work to do in Preference Activity). A bit nicer for the user, but way more work for the developer would be custom dialogs for each preference with more text and/or a help button. Is there a better solution or even an officially recommended best practice?

I got my x10 yesterday and played all day long. Everything was fine untill I try to upgrade the software.I used Sony Update Service software and it give error at the middle of the process.Now, I got explanation point on my screen when I turn it on. I can't do anything.Any ideas, how to fix?

Recently I've started to develop Android Soft Keyboard and got some problem with preferences. How to add a preferences to Android setting app? I've searched almost all the source code of AnySoftKeyboard, but haven't found anything what would add them to Settings app.

I'm new to Android ndk and i didn't understand yet which are the differences between static and shared library. Could you explain me what these differences are? When developing a library how could i choose one of them?

I have a cross-platform C library that I need to compile for Android as a *.so file. The library consist of many .c and .h files, and it use autotools as it's buid system. (./configure && make dep && make). Afaik, the library does not depend on other libraries, other than libc and OpenSSL (which should be present on Andriod).

I'm trying to find the simplest (read fastest in terms or not needing to read hundreds of pages of manuals and then apply try && fail brute-force approaches to complete the task) way of getting the library off my machine in source code form, and into the Android phones as a .so. The library will eventually be accessed from Java's native library interface. For development, I have both Windows and Debian machines on my desk.

So I use my Eris to sync my Google Calendar which works fine. But I am trying to be able to see my wife's Google Calendar on my phone as well. I have the calendar shared with full access to myself, but I still cannot see it on my phone, although I see if when I log in to Google Calendars. What am I doing wrong? Is it possible to see shared calendars on the Eris? If so, how do I go about doing it?

After installing the smokedglass v6 rom, it deleted some apps, when i try to reinstall the apps that got deleted, i got an error that says "Installation error, Missing shared library." i went into manage apps to make sure they aren't there, and i used root explorer to delete any trace of the apps, yet i still get this error.

I have next situation: After installing application it has to init settings from server. And while it is not has right preferences it has to wait. I have several receivers and service - I don't want to check for initialization in every action in these components - I think there have to be better solution.

And I was wondering is it possible for me to then use this preference in code so I can update it via downloading an xml file? So I currently display the above preference in a PreferenceActivity, which works fine, however I want to be able to update the setting by downloading a new setting every week from the internet. So my question is how do I open this preference in code and set its value to the new downloaded value?
